To all 10710212 it or (1/3] cori'ccrn:

Be it known that I, Gnor. on M. (,iunnnlizv'r, a citizen oi the United States. residing at .lf anville, Pittsylvania county, Virginia, have invented certain new and useinlimproven'ients in Automatic Pieture-Exhibiting Apparatus; and I do hereby declare the tellon inc; to be a full, clear, and exact description oi' the Lame, re'i'erenee being had to the accoin nmyine drawings, forming a part of this spe ification, and to the figures and letters of reference marked thereon.

This invent-ion relates to improvements in autonnitie picture projecting or exhibiting devices, the objects being to provide eilicient mechanical means for successively priiisenting a. series oi pictures in the iield of the projectin; lens or in the tield of observation.

ihe invention consists in certain novel details oi construction and combinations and arrai'igen'ienis 0i. mrts, all as will be now described and pointed out particularly in the appended elaims.-

in the accompanying drawings: Figure 1 is a top plan view oi' the working parts oi an apparatus embodying the present in'iprrwements. Fig. 2 is a section in a vertical plane on substantially the line 2-2, Fig l. i Fig. 3 is a detail view on an enlarged scale showing particularly the intermittent feed. mech anism for the iarrier and a supplemental electrically controlled releasing mechanism.

.llike (.-llttl'2l('.i1(-TS ol" rel'erence in the several lieu indicate the same parts. I

In the ap niratns oi' the present invention a rotary carrier mounted on avertical axis and having a series of radially arranged hold ers or gnideways for the picture slides is e1n ployed in eonneetii'in with mechanism 'i'or successively moving the ictnres radially into the iield of observation or field of the projecting lenses.

The carrier is prel'erahly io'rined. by circular top and bottom plates A. ermineetcd by posts A and mounted. on a central axis or journal screw 19 and'an annular bea-rine' such as the ball bearing 13 'i'or holding: the parts in correct level position. The proximate faces of the plates are provided with radial grooves (Lii'orininp the radial holders or guide ways for the picture slides i.

At one point in the rotation of the carrier each holder or guii leway is brought into al inement with a 'lixeil guide l) of proper i'orn o roceivef'and support the pieturqslide when ing: the outer edgcs oi the slides and a terwardly projecting arm it for engaging the inner edges oi the slides". The arm h ex tendsthrough a central opening oil, the top plate oi the carrier and oi suilicient lene't h to pass between the plates in advancing the slides to their projected position.

The recipriicatory carrmgre is prcierably rctracted by a spring ll, but is advanced to project a slide and hold the same projected for adetermined time by a spring motor ll having a power shaft 11 carrying: a mutilati-d gear M meshing with a. rack .ll'- on the carriage H. A fan governor if coni rels the speed at which the spring motor may run, and also forms a convenient part with which the stop projection n on the control ici'cr may engage to arrest the movement oi the motor. 7

A. cam hi on the power shalt below the mutilated gear serves h hold the confi-ol lever out oi engagement with the inn durin; the running: pm'iod oi the .inotor, while a notch or recess in permits the lever to ad- 'ance under the iniiuence oi its spring! 711 into position to stop the crater at the proper point inthe rotation oi the shalt.

in addition to the mutilated gear and 'am, the power shalt carries a i'eed arm or projection .l for advancing the carrier step by step. The arm or projection l engages a. lever l", carrying a. spring pressed pawl l adapted to engage teeth or notches, prei'eraiiy thc end walls of the slots lornL-inc the slidcwais in the upper plate of the carrier, as shown clearhr in Fig. 3.

The relative arrangement oi' the mutilated gear, cam Iii and i'ceilyn'ejcction P, and the cooperating parts is such that whcn the stop levo r is permitted to advance by entering the notch in theeam M to engage the fan and arrest the motor, the mutilated gear has advanced the carriage to the position shown in,

Fig. l with a slide projected, and the feed projection a short distance away from its cooperating lever. If the control lever be now tripped or moved back out of engagement with the fan, as by a clock train Q and pro- H. During the time the space in the mutilated gear is passing'the rack, the feed arm engages its lever andadvances the carrler the distance between ad acent slides, then the mutilated gear again engages the rack bar and advances the carriage together with the new slide which has been brought into position. by the movement of the carrier, and finally, just as the parts reach the first position the cam M permits the stop lever' to again engage the fan and stop the motor. In order to bring the carriage to rest without undue shock a dash no t or air check S is coni'iected with the car or is adapted to be a thereon, as will be sin is preferably employed to release the spring motor periodically, say once a minute, it may be desirable in some 12 tances to control the same from a distance and hence, as shown in Fig. 3, I prefer to mount an armature T on the control lever in position to be drawn toward an electromagnet "l" for releasing the lever, and the' magnet may be energized by a circuit adapted to be established. or broken at any convenient point and either manually or by well known automatic means.

Having thus described the invention, what I claim as new and desire to secure by Letters-Patent, is:

1. In an automatic picture exhibiting device, the combination with a rotary carrier journaled on a vertical axis and having radial guides for picture slides, of a reciprocatory carriage, motor mechanism for reciprocating said carriage and moving the carrier step bystep, and projections embracing the picture slides for positively projecting the same beyond the carrier and returning them to normal position in thecarrier.

2. In an automatic picture exhibiting device, the'combinationj with a horizontall 4 arranged rotary carrier journaled on a' vert1- cahaxis and having horizontal radial guides for picture slides, of a reciprocatory carriage" movable radially of said carrier and having projections adapted to engage opposite edges of the p ture slides for moving the latter positively nboth directions, motor mechan ism for reciprocating said carriage and mov-' ing the carrier stepby' stepto bring the picof the carrier, and a motor mechanism for reciprocating the carriage embodying a rack bar and a motordriven mutilated gear and a carrier feed mechanism operated to feed the carrier while the gear is out of mesh with the rack bar.

a. In an automatic picture exhibiting apparatus, the combination with a rotary car' rier having radially arranged picture slide guides, of a reciprocatory carriage having projections between which the slidesare brought by the rotation of the carrier, a rack bar connected with the carriage, a motor driven mutilated gear adapted to mesh with the rack bar and a spring for moving the carriage in opposition to the movement imparted by the gear.
